Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Scrapped Ammo is worth keeping when a crafting path needs ammo salvage instead of live rounds.
Scrapped Ammo earns space when the next bottleneck is ammo crafting, not live firefights. It matters because so many shell and cartridge recipes burn salvage first, which means one stack can quietly unblock several later crafts. It still should not be carried out of habit. If the crew is low on working ammo, heals, or extraction margin, dead ammunition parts are an easy thing to cut before living through the run.
You mainly pull it from Weapon Crates, and it stays useful because a lot of ammo recipes still want salvage before they become real rounds.
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Coral Chunk feels useful early because you keep finding places to spend it instead of watching it rot in storage.
Coral Dust starts feeling good the moment you realize it is not random filler and actually feeds ammo people want to craft.
Fabric matters when the next recipe has already moved past scraps, so it wins the slot only if a higher-grade textile input is actually waiting.
Fabric Scraps only deserve cargo space when a live recipe still accepts scraps; otherwise they lose to fuel, heals, and ammo fast.
Gunpowder is a keep-or-drop material, and it wins the slot only when ammo or explosive crafting is already part of the plan.
High-Grade Gunpowder earns cargo space only when a real craft or trade plan already needs it more than the survival stacks competing for the same slot.
Leviathan Meat is the easier Leviathan material to justify, because Food Crates drop it and each stack still sells for 14 Crowns per piece at the pawn shop.
Its best value appears when one stack is about to become real ammunition. That is the point where salvage finally stops being dead weight and starts solving the next run.
When no current recipe, research node, trade target, or Trampler upgrade needs it, fuel, heals, and matching ammunition move ahead in the pack.
It is worth carrying out when your next ammo craft still needs salvage and you are not already bleeding for lack of working rounds, heals, or extraction space.
It should lose that battle when the crew needs immediate combat supplies more than future crafting value, because salvage does nothing for a fight you still have to survive.
